Hi,

I'm wondering what's the status of this patch?  

if this has hit a subsystem tree yet?  0.75 watts power savings sounds
really cool, but it doesn't seem to be in Linus's mainline yet.  Has
it hit a subsystem tree yet, or is there some issue that still needs
to be resolved before it can go it?

Thanks, regards,
